In this study, we developed a centri‐voltammetric electrochemical sensor for glutathione (GSH) detection. For this purpose, N,N′‐2‐octyloxy‐1‐methyl‐2‐oxoethyl)‐(‐2,4‐thiolbutyloxy)‐1‐methyl‐2‐oxoethyl)‐3,4 : 9,10‐perylenetetracarboxyldiimide (PDI‐C4SH) molecule was used as a carrier molecule for the first time. This molecule, interacted with the thiol ends of GSH and formed a disulfide bridge. By this way, PDI‐C4SH improved the accumulation of GSH onto the electrode surface and increased the sensitivity of the detection protocol. All the electrochemical measurements were carried out with differential pulse voltammetry by using a carbon paste electrode. The linear response was obtained in the range of 0.05 mM and 5 mM for GSH concentration (R2=0.9966) while limit of detection value was calculated as 0.017 mM. For the sample application experiments, developed system was applied to the determination of GSH in red wine samples by using the standard addition method, and an acceptable recovery value of 99.03 % was obtained.

The fluorescent materials have sparked a lot of research interests due to their unique electronic, optical and chemical characteristics. Here, we are intended to present a simple and facile synthesis of novel orange emitting thiazole‐pyridone fluorescent tag (TPFT) by a simple diazo coupling reaction and the structural elucidation was carried out by IR, NMR (1H and 13C), UV–Vis, photoluminescence and HR‐MS spectrometry. The solvatochromic behaviour of the TPFT offered crucial information about the formation of hydrazone and azo tautomeric forms. The DFT simulations are computed to calculate HOMO‐LUMO energy gap (3.028 eV) of TPFT along with MEP and RDG analyses. Comprehensive LFP visualization is revealed under both normal and UV light conditions (365 nm). The cyclic voltammetry (CV) and differential pulse voltammetry (DPV) were used to analyse the electrochemical behaviour of the TPFT‐modified glassy carbon electrode (MGCE) and exhibited a lower detection limit of 7.89 × 10−8 M (S/N = 3) with a linear range of 0.5–8.0 μM for DA detection. The live‐cell imaging study of TPFT showed a strong blue emission at 453 nm, which generally indicates the existence of fluorescence stability.
